Well, nothing's wrong there, and the same could be done with Java
before. However, having a consistent deprecated string everywhere allows
easier eg. automatic finding of such methods from documentation.
Decorators also help here, but that requires version 2.3 or newer (which
usually isn't a problem, but can be)
Hey! I hadn't realized category parameter nor stacklevel in warnings module
(just used a few times, never read the doc because I didn't need to). Neat,
thanks.
